AUGUSTINE SAOKETT, OF NEW YORK, N. Y.

PROCESS FOR COATING PAPER AND CLOTH.

SPECIFICATION formingpart of Letters Patent No. 231,450, dated August 24, 1880.

Application filed January 7, 1880.

To all whom it may concern:

Be it known that I, AUGUSTINE SAOKETT, a citizen of the United States, residing at No. 232 East Fiftieth street, New York city, in the county of New York and State of New York, have invented a new and useful Process for Coating Paper and Cloth, which invention has not been patented to myself or to others, with my consent or knowledge, in a foreign country; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a simple and effectual means of coating paper and cloth on one side and preserving the opposite side free from the coating material.

This invention is especially useful where the coating material is a cement which cannot well be applied with brushes, either on account of its semi-fluid consistency or the necessity of applying it at a high degree of heat.

I accomplish the object sought by drawing the web of paper or cloth across a non-revolving bar or still bar, and bringing the opposite side of the web, on the line which is in contact with the still bar, into contact with the ocment, either by partly immersing the still bar in the "at of cement or by adjusting it at the proper distance from a cylinder which revolves in the cement, being partly immersed therein, and thus conveying it to the paper.

The still bar may be so adjusted with reference to the cylinder that the cylinder will evenly distribute and also remove the superfiuous cement, or the distribution and removal of excess may be eft'ectcdby means of a scraper or roller brought to act on the coated side before the web leaves the still bar.

When the method adopted is to partly immerse the still bar in the vat of cement the distribution and removal of excess is readily accomplished in a similar manner by means of a scraper or roller brought to act on the coated side before the paper leaves the still bar.

It will be found that by this process the pure side of the paper or cloth will be preserved almost perfectly free from the coating material.

In its application to the coating of cloth, it is obvious that the cement must be of such consistency as not to penetrate through the web.

In the drawing, A represents a roll of paper or cloth; B, the still bar; B, scraper; G, revolving cylinder; D, vat of cement; d at, surface of cement, showing the still bar partly immersed. When the cylinder 0 is employed the upper part is raised above the surface of the cement and at the proper distance from the still bar B.

Having fully described my invention, what I desire to claim and secure by Letters Patent is 1. The process of coating one side of a web of paper or cloth by passing the web under a still bar which is partly immersed in the coatin g material, substantially as above described.

2. The process of coating one side of a Web of paper or cloth by drawing the web partly around a still bar and applying the cement to the opposite side of the web on the lines of contact with the still bar, substantially as above described.

3. The distributing and removing of excess of material by drawing the web between a still bar and scraper or roller, substantially as above described.

AUGUSTINE SAGKETT.
